Abstract

Abstract A colo-rectal evacuator is disclosed for mechanically removing waste material through a patient's rectum. The evacuator includes a rectal tube with a distal nozzle end that is designed to be inserted into the patient's anal canal; an adjacent inflatable bladder that is adapted to abut feces inside the canal and remove them when the tube is pulled by a trained professional; a lower balloon that is adapted to burst and provide lubrication to ease the removal; and a collecting bag that surrounds the tube and immediately stores the feces upon their removal. After the distal end is inserted into the patient, the bladder is inflated with air and the balloon is pumped up with lubricant. Continued inflation of the balloon causes it to burst and the lubricant to spread among the trapped feces. When the tube is subsequently pulled, the bottom of the bladder pushes the feces out of the patient's rectum.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 147 words
A colo-rectal evacuator comprising: a. a collecting bag having a top and bottom, said bag having an opening at its top that is adapted to overlie a person's perineum and a fastening means near its top for removably connecting the bag to the person; b. a flexible rectal tube that passes through and is attached to the bottom of the collecting bag, said tube having a distal nozzle end that is housed within the bag and adapted to be inserted into the person's anal canal; c. an inflatable bladder that surrounds and is attached to an upper portion of the tube adjacent the tube's distal end; d. a balloon that surrounds and is attached to an upper portion of the tube adjacent the inflatable bladder; and e. wherein the tube has three internal conduits that are respectively connected in fluid communication with the nozzle, balloon and bladder.
Claim 2
Dependent Claim 147 words
A colo-rectal evacuator comprising: a. a collecting bag having a top and bottom, said bag having an opening at its top that is adapted to overlie a person's perineum and a fastening means near its top for removably connecting the bag to the person; b. a flexible rectal tube that passes through and is attached to the bottom of the collecting bag, said tube having a distal nozzle end that is housed within the bag and adapted to be inserted into the person's anal canal; c. an inflatable bladder that surrounds and is attached to an upper portion of the tube adjacent the tube's distal end; d. a balloon that surrounds and is attached to an upper portion of the tube adjacent the inflatable bladder; and e. wherein the tube has three internal conduits that are respectively connected in fluid communication with the nozzle, balloon and bladder.
Claim 3
Dependent Claim 14 words
The evacuator of claim 1 wherein the nozzle comprises a hollow, doughnut-shaped, perforated ring.
Claim 4
Dependent Claim 24 words
The evacuator of claim 1 wherein the fastening means includes two pairs of tie bands for tying the bag onto the person's upper thighs.
Claim 5
Dependent Claim 21 words
The evacuator of claim 3 wherein the fastening means further includes an adhesive strip for sticking the bag onto the person.
Claim 6
Dependent Claim 102 words
A rectal evacuator comprising: a collecting bag; a flexible rectal tube attached to one end of the bag and extending through the bag interior, wherein said tube has a distal end with a nozzle opening that is adapted to be inserted into a patient's rectum through an opening in the other end of the bag; a balloon and an inflatable bladder that are spaced apart and attached to an upper end of the tube adjacent the tube's distal end; and three conduits formed in said tube which are respectively in fluid communication with the nozzle opening, the balloon, and the inflatable bladder.
Claim 7
Dependent Claim 102 words
A rectal evacuator comprising: a collecting bag; a flexible rectal tube attached to one end of the bag and extending through the bag interior, wherein said tube has a distal end with a nozzle opening that is adapted to be inserted into a patient's rectum through an opening in the other end of the bag; a balloon and an inflatable bladder that are spaced apart and attached to an upper end of the tube adjacent the tube's distal end; and three conduits formed in said tube which are respectively in fluid communication with the nozzle opening, the balloon, and the inflatable bladder.
Claim 8
Independent Claim 201 words
A method of mechanically evacuating waste colon material through a person's rectum, said method comprising the steps of: a. uncovering a flexible rectal tube that is housed inside a collection bag and attached to the bottom thereof; b. lubricating a distal end of the tube; c. gently inserting the tube's distal end into a person's rectum and pushing upwardly for approximately 10 centimeters; d. fastening the collection bag onto the person so that a top opening of the bag overlies the person's perineum; e. gently pushing the tube further into the rectum; f. inflating a bladder inside the rectum, wherein the bladder surrounds and is attached to an upper portion of the tube adjacent the tube's distal end; g. inflating a lower balloon inside the rectum with lubricant until the balloon bursts, wherein the balloon, prior to inflation, surrounds and is attached to another upper portion of the tube adjacent the bladder; h. pulling the tube slowly and gently so that a flat surface of the bladder abuts feces in the rectum and pushes them out; i. collecting feces inside the bag as they are removed; and j. removing the plastic bag from the perineum after the fecal mass is collected.
Claim 9
Independent Claim 201 words
A method of mechanically evacuating waste colon material through a person's rectum, said method comprising the steps of: a. uncovering a flexible rectal tube that is housed inside a collection bag and attached to the bottom thereof; b. lubricating a distal end of the tube; c. gently inserting the tube's distal end into a person's rectum and pushing upwardly for approximately 10 centimeters; d. fastening the collection bag onto the person so that a top opening of the bag overlies the person's perineum; e. gently pushing the tube further into the rectum; f. inflating a bladder inside the rectum, wherein the bladder surrounds and is attached to an upper portion of the tube adjacent the tube's distal end; g. inflating a lower balloon inside the rectum with lubricant until the balloon bursts, wherein the balloon, prior to inflation, surrounds and is attached to another upper portion of the tube adjacent the bladder; h. pulling the tube slowly and gently so that a flat surface of the bladder abuts feces in the rectum and pushes them out; i. collecting feces inside the bag as they are removed; and j. removing the plastic bag from the perineum after the fecal mass is collected.
Claim 10
Dependent Claim 28 words
The method of claim 6 wherein the method further includes the step of spraying lubricant into the person's rectum through a spray nozzle in the tube's distal end.
